The London Underground is an iconic underground metropolitan railroad located in London, England. In addition to shaping the city of London above it, the Underground also influenced metropolitan railroads around the world. Many nations modeled their subway systems after London's, which is also known as the Tube, due to the characteristic shape of the subway tunnels. The first line was completed in the late 19th century.

The total network that makes up the London Underground is 253 miles (408 kilometers) long. About 976 million rides are taken on it each year in 4,070 subway cars. It began in 1863, when service was first opened between Paddington Station and Farringdon Street. The system has continued to expand, with periodic constructions of new lines and retrofitting of old ones to better serve people in the city.

Construction on the metropolitan railway system, which came to be known as the London Underground, began in the Victorian era in response to increasing traffic congestion. The city's growing population made traveling in London very difficult, and it was thought that an underground railway would solve many congestion problems. The system expanded rapidly, and included 12 separate lines by 2006.

Initially, the lines were constructed using a cut and cover technique. This involved completely excavating the dirt, building a supported brick arch, and covering the arch. This technique was time consuming and contributed to congestion as well, as it blocked off vital roadways. Later, a system similar to that used in coal mining was used, where tunnels were excavated and supported with beams before being brick lined.

The first line to be completed was the Circle Line, which was finished in 1884. Other lines followed quickly, including the Central Line, Bakerloo, and Hammersmith and City. Initially, the Underground used steam trains, but began to convert to electric trains in the early 1900s. Electronic ticket machines were introduced in 1918, and the system continued to be at the forefront of metropolitan railway innovation.

The London Underground's extensive network was employed for use as underground bomb shelters during World War II. Britons of all ages and classes sheltered underground during numerous bombings of London. Expansion on the system ceased during the war, with partially completed lines being used for storage and basic manufacturing. In 2003, the Underground was integrated into the Transport for London system, which is aimed at increasing efficiency and capability of London's transit services.

The Tube also has a unique map, designed by Harry Beck in 1933. Beck realized that a geographically accurate and properly scaled map would be difficult for travelers to read. His map simplified the system to its essence, color coding the various lines and smoothing out their routes so that the entire network could be represented simply and plainly. Maps styled after his are used for transit systems everywhere to quickly convey basic information about routes to travelers.

The London Underground also has several “ghost stations” that were closed for various reasons, but still exist. Some of them are like time capsules perfectly capturing the moment at which they were closed, while others have been more or less erased from history. Tours of the disused stations are sometimes held, and they are an interesting look into the heart of the subway system.

@anon5655-- I don't know the entire history of the Underground but I do know about the East London line. It used to be the Thames Tunnel. Sir Marc Brunel built it in the 1840s. I believe this was the first piece of the Underground that was built. It was first a tunnel under the water, later it was a railroad and eventually it became the Underground.

I believe the reason for building it was because there were too many horse drawn carriages on the roads. It was too crowded.

@fify-- That's cool. I'm planning to do the same because I have a connecting flight from London. What are London Underground fares like?

I've been on the London Underground once. I had several hours at London Heathrow airport once and went out to see London a bit. The Underground actually runs from the airport so that was really convenient. I went to Piccadilly Circus and had lunch there.

The thing I remember the best about London Underground is "mind the gap!" This is what was announced on the Underground every time the doors opened and closed. It's because there is this gap between the metro and platform.

how much did the first, oldest London subway cost?

My grandson wants to know who had the idea for the London underground rail system, who designed it and who built it - anyone know?
